2 Samuel 21:8-13

However, he took Armoni and Mephibosheth, the two sons that Rizpah the daughter of Aiah had borne to Saul; he also took the five sons of Saul's daughter Merab, whom she had borne to Adriel son of Barzillai, who was from Meholah. David handed them over to the people of Gibeon, who hanged them on the mountain before the LORD—and all seven of them died together. It was late in the spring, at the beginning of the barley harvest, when they were put to death. Then Saul's concubine Rizpah, the daughter of Aiah, used sackcloth to make a shelter for herself on the rock where the corpses were, and she stayed there from the beginning of harvest until the autumn rains came. During the day she would keep the birds away from the corpses, and at night she would protect them from wild animals. When David heard what Rizpah had done, he went and got the bones of Saul and of his son Jonathan from the people of Jabesh in Gilead. (They had stolen them from the public square in Beth Shan, where the Philistines had hanged the bodies on the day they killed Saul on Mount Gilboa.) David took the bones of Saul and Jonathan and also gathered up the bones of the seven men who had been hanged.
